Abstract
Description
본 발명은 일반적으로 많이 사용하는 트랜스 포머 소재인 철심 코어에 관한 것으로 지금까지는 규소 강판의 박판을 사용하여 먼저 프레스로 E와 I의 철심을 만들어 이것을 수 작업으로 적층하고 함침의 공정을 거치는 일련의 공정으로 진행하였다. 이 과정에서 얇은 판을 적층하는 공정의 어려움과 함침으로 인한 공정의 복잡함 및 함침 재료의 투입, 폐기 시 환경의 영향 그리고 부적절하게 이루어진 함침으로 인하여 트랜스 포머 코어의 절연 상태 불안 등 많은 문제점이 발생하였다.The present invention relates to an iron core core, which is a transformer material commonly used. Up to now, a series of processes in which iron cores of E and I are first made by pressing using thin sheets of silicon steel sheets, are laminated by hand, and subjected to impregnation Proceeded to. In this process, many problems, such as the difficulty of laminating the thin plate, the complexity of the process due to the impregnation, the input of the impregnating material, the influence of the environment upon disposal, and the improperly impregnated impregnation caused the insulation core instability.
이에 본 발명은 상기 문제점을 해소하기 위한 목적으로 E코어와 I코어를 블랭킹하기 위한 일정 간격의 금형을 배치하고 이 배치된 금형에 의하여 피어싱과 엠모싱 블랭킹이 한 공정 한 공정 씩 도4에 보인 바와 같이 기술적으로 작업이 되도록 하고 엠보싱의 방법은 사각형의 볼록 돌기를 생성하여 이 돌기들에 의하여 E코어와 E코어를 적층할 때나, I코어와 I코어를 적층할 때 정확히 적층 되면서 적층 후에도 적층 시에 상하부의 돌기가, 조립할 시 압력에 의하여, 하부의 돌기에 상부의 돌기가 팽창되면서 다시 분리가 어려운 구조로 될 수 있도록 하고, 이 돌기에 의한 적층 공정으로 인하여 함침 공정을 생략할 수 있어 함침 공정에 대한 비용을 절감하고 자동화가 가능하며, 대량 생산을 함으로서 관련 산업의 경쟁력에 기여하고 자 한다.In order to solve the above problem, the present invention arranges molds having a predetermined interval for blanking the E core and the I core, and the piercing and embossing blanking are performed by the arranged mold, as shown in FIG. 4. In the same way, the embossing method generates rectangular convex protrusions, and when the E cores and E cores are stacked by these protrusions or when the I cores and I cores are stacked, The upper and lower projections, due to the pressure at the time of assembly, the upper projections on the lower projections can be expanded to a structure difficult to separate again, and the impregnation step can be omitted due to the lamination process by the projections. We want to contribute to the competitiveness of related industries by reducing costs, automating and mass production.

이하 예시된 도1의 본 발명에 따른 본 발명에 따른 제작 흐름 도 기준으로 설명하면. 일정 폭으로 슬리터(slitter)된 규소 강판이 언 코일러에 투입되어 레벨라와 피더를 거쳐 평판으로 일정 길이로 프레스에 투입된다. 그리고 2단계 이상의 순차적 금형에 의하여, 먼저 페이싱 공정(A)을 거치고 다음 본 프로그레시브 공정에서 기준마크인 파이롯트 공정(B)에 의하여 파이롯홀을 만들고 다시 도4에 보인 것과 같이 일정길이로 피더에의하여 계속 진행하여 엠보싱 공정(C)으로 원형 혹은 사각의 적층용 엠보싱 돌기(3)를 성형하고, 그 다음 I코어공정(D)에서 I 코어(2)를 블랭킹하고 블랭킹과 동시에 적층용 엠보싱 돌기(3)에 의해 바로 하부에 I 적층 코아(5) 형성된다. 다음 공정으로 E-1 코아 공정(E)에서 I코어가 블랭킹되고 없는 상태의 두 개의 E형 코아가 메인 스트립에 위치한대로 이송해온 것을 먼저 E-1을 블랭킹하여 I코아의 적층 방법과 같이 적층하고 E-2 코어도 같은 방법으로 적층하여 I코어 2블륵과 E-1, E-2 등 도2에서 보인 바와 같은 블록이 2블록으로 2세트의 단위로 E와 I블륵이 형성되어진다.Referring to the production flow diagram according to the present invention according to the present invention illustrated in Figure 1 below. A slitter of a certain width slitter is introduced into the uncoiler and fed into the press through a leveler and a feeder into a flat plate at a predetermined length. Then, by the sequential mold of two or more steps, first through the pacing process (A), and then by the pilot process (B), which is the reference mark in the present progressive process, the pilot hole is made, and continues by the feeder at a predetermined length as shown in FIG. To form a round or square laminating embossing projection 3 in the embossing process (C), and then blanking the I core 2 in the I core process (D) and blanking the lamination embossing projection (3) simultaneously. I laminated core 5 is formed immediately below. In the next process, two E-type cores in the E-1 core process (E) which are blanked and without I cores are transferred as located on the main strip. The E-2 cores are also stacked in the same manner to form two blocks of I-core and two blocks such as E-1 and E-2 to form two sets of E and I blocks.
본 발명에 의해 제작된 E-I 블록 코어는 블록 코아를 만들기위하여서는 필연적으로 발생하는 규소강판의 손실(Loss)을 최소로 설계 제작됨으로써 원자재 인상을 최대한 억재 하였으며 아울러 함침 공정을 삭제함으로서 생산성을 향상함과 함침에 소요되는 비용을 절감할 수 있고 함침으로 인한 제 문제점을 제거할 수 있으며 본 발명에 의한 자동화가 가능하여 대량 생산 체재로 제작 할 수 있는 등 상기 설명한 본 발명의 장점들에 의하여 소재 비의 절감 및 관련산업의 경쟁력이 향상되어 산업에의 파급효과는 지대하다고 본다.The EI block core manufactured by the present invention is designed to minimize the loss of silicon steel sheet, which is inevitably generated in order to make a block core, thereby suppressing the impression of raw materials as much as possible, and also improving productivity by eliminating the impregnation process. The cost of impregnation can be reduced, the problems caused by impregnation can be eliminated, and the material cost can be reduced by the advantages of the present invention as described above. And the ripple effect on the industry is considered to be huge as the competitiveness of related industries is improved.
